(a) To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other such guidance that may be issued after the date of this Agreement (collectively, “Section 409A”). Notwithstanding any provision of this Agreement to the contrary, in the event that following the date of this Agreement, the Company determines that any compensation or benefits payable under this Agreement may be subject to Section 409A, the Company may adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other actions that the Company determines are necessary or appropriate to preserve the intended tax treatment of the compensation and benefits payable hereunder, including without limitation actions intended to (i) exempt the compensation and benefits payable under this Agreement from Section 409A, and/or (ii) comply with the requirements of Section 409A, provided, however, that this Section 9 does not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions. In no event shall the Company, its affiliates or any of their respective officers, directors or advisors be liable for any taxes, interest or penalties imposed under Section 409A or any corresponding provision of state or local law.

Any payments subject to Section 409A that are subject to execution of a waiver and release which may be executed and/or revoked in a calendar year following the calendar year in which the payment event (such as termination of service) occurs shall commence payment only in the calendar year in which the consideration period or, if applicable, release revocation period ends, as necessary to comply with Section 409A. All payments of nonqualified deferred compensation subject to Section 409A to be made upon a termination of service under this Agreement may only be made upon Consultant’s “separation from service” (within the meaning of Section 409A).

(c) Notwithstanding anything to the contrary in this Agreement, no compensation or benefits shall be paid to Consultant during the six-month period following Consultant’s “separation from service” with the Company (within the meaning of Section 409A) if the Company determines that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier

4

date upon which such amount can be paid under Section 409A without resulting in a prohibited distribution, including as a result of Consultant’s death), the Company shall pay Consultant a lump-sum amount equal to the cumulative amount that would have otherwise been payable to Consultant during such period (without interest).

10. Governing Law. This Agreement shall be construed under the laws of the State of North Carolina, both procedural and substantive.

12. Headings. The headings in this Agreement are provided solely for convenience, and are not intended to be part of, nor to affect or alter the interpretation or meaning of, this Agreement.

13. Severability.
